Summary
Brief summary (as posted)
The goal of this study is to understand how people understand risk from genetic testing. The investigators want to understand what visual aid best helps people accurately assess risk. The investigators also want to understand how people relate risk to their health. The main questions the study aims to answer are: 1. Which visual aid most accurately show genetic risk? 2. How do people perceive risk related to genetic test results? 3. What factors are associated with people discussing their results with family? Participants will: 1. receive of of two visual aids showing risk 2. state their estimation of risk 3. answer questions about how they feel about risk and sharing information with family
